MAN Energy Solutions - Wikipedia
The company develops and manufactures two-stroke and four-stroke diesel engines , [ 3 ] as well as gas turbines , steam turbines , and compressors. MAN Energy Solutions also offers turbochargers , propellers , gas engines , and chemical reactors. MAN originated from three German predecessor companies, the St. Antony ironworks in Oberhausen, Sander'sche Maschinenfabrik.
Antony was founded in and became Gutehoffnungshütte GHH in , after several changes in ownership and restructuring. In , following several experiments on the four-stroke engine by Hugo Güldner , the first two-stroke diesel engine was built.

After the turn of the century, MAN developed the first diesel engine with an opposed-piston engine design. MAN built the first diesel power plant in Kyiv in In , Gutehoffnungshütte acquired a majority stake in MAN, creating a conglomerate that encompassed traditional ironworks, modern mechanical engineering, and the production of various commercial vehicles. The conglomerate operated under the abbreviation GHH.
During World War II, the company experienced revenue growth as Gutehoffnungshütte became involved in armament manufacturing. Production primarily included tanks , diesel engines for submarines, and shell casings in support of the Nazi war effort. After global shipbuilding increasingly shifted to Far East Asia in the s and engine manufacturers' development costs rose, several large diesel engine manufacturers withdrew from the market at the end of the s.
Since then, the development of four-stroke engines has been carried out in Augsburg, while two-stroke engines are designed in Copenhagen.

In , the company commissioned a methanisation reactor for Europe's first power-to-gas plant in Werlte. Furthermore, the company announced its commitment to the development of low-emission gases as ship fuels. In , MAN Energy Solutions began developing a seawater-based heat pump for Esbjerg , Denmark, [ 27 ] which utilizes seawater for heat generation. In , the company conducted trials using carbon-free ammonia as fuel with a two-stroke diesel engine.
As a result, MAN Energy Solutions announced plans to provide ammonia propulsion for maritime operations by Møller-Mærsk shipping company with methanol engines. In , MAN Energy Solutions signed a contract with Karpowership , Istanbul, for the delivery of 48 dual-fuel engines for their power ship fleet, with the engines to be distributed across multiple floating power plants.
MAN Energy Solutions manufactures large engines for ships and power plants, including gas engines used, for instance, in gas power plants for electricity and district heating generation. Additionally, the product range includes energy storage products and the construction of large heat pumps. MAN Energy Solutions is also involved in equipping container freighters with eco-friendly methanol engines.
MAN Energy Solutions is also working on the development of a marine engine based on the combustion of climate-neutral fuels such as methanol or ammonia. Two-stroke engines are developed at the company's base in Copenhagen.
The engines propel large container vessels , freighters and oil tankers. Low-speed diesel engines do not require a transmission system because they are directly connected to the propellers by drive shafts. MAN Energy Solutions also offers medium-speed four-stroke engines [ 43 ] that can be operated using liquid or gaseous fuel. Medium-speed engines [ 44 ] are deployed to propel all types of merchant vessels , but are also used in passenger ships due to their compact nature and their amenability to flexible mounting.

As well as cruise liners , other areas of use for medium-speed engines include specialist vessels such as tugs , dredgers or cable-laying ships. Smaller medium-speed four-stroke engines are also used in high-speed ferries and naval vessels. Additionally, the company provides complete propulsion systems, including the main engine, gearbox and propeller. MAN Energy Solutions builds exhaust-gas turbochargers [ 48 ] using single-stage radial and axial turbines to create high charging pressures.
The performance spectrum of these chargers, which are used both in two-stroke and four-stroke marine engines and in stationary systems, ranges from around kW to 30, kW of engine power.
